Application filed June 11, 1915. Serial No. 33,459.

To all whom it mag concem.'

Be it known that I, JAMS Knox POLK BINGAMAN, a citizen of the United States of America, and resident of 2210 Fulton avenue, Cincinnati, in the county of Ham1lton and State of Ohio, ('ost-ofiice address Vine and Sixth streets, incinnati, in the county of Hamilton and State of Ohio,) have invented certain new and useful Improvements in .Paper Cartons; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.

My invention relates to paper cartons and it has for its object the improvement of such paper cartons whereby they aresimplified and rendered more eflicient in action.

The novelty of my invention consists in the combination and sub-combination of the parts as will be hereinafter set forth and specifically pointed out in the claim. Figure 1 represents the blank from which my improved box is made. Fig. 2 is a perspective View of the box when folded together and locked with'my improved "curved lock.

The dotted lines in Fig. 1 indicate the points at which the blanks will crease in forming the box. The material which I employ for making this box consists of card, straw, or paste board. The blank shown in Fig. 1 is composed of card or pasteboard. This blank is scored as indicated so as to form the cover flaps and themain end flaps of the box. The dotted lines, which indicate the points at which the blank. will be creased in forming the box also serve in Fig. 1 to space ofl the blank into the several'parts of the box, which said parts are as follows: A indicates the bottom; B B the sides; 0 the four corner and end flaps; D the main outer end flaps; E E the two inner cover flaps and F F" the. outer cover flaps. The blank is furtherformed with slits or catches G on the four corner and end flaps, C and with v slits or catches E on the-twoinner. cover flaps, E E, also slits or catches" F on the two outer cover flaps F, F.

Particular attention is called to the form of my catches which are curved shaped with a round hole M at the inner end of the curve. The curved slits or catches are tanhole at the end of the curved shaped slits or catches'is the feature that makes this lock so positive. When the two holes at the end of the slits or catches engage they will not become disengaged of their own accord. The only way you unlock them is to press them together so the two tangent sides come together when they can be unlocked. In forming the box 'shown .in Fig. 2 from this blank the sides B are turned up on the lines G and brought at right angles to the bottom A., The corner flaps C are then turned in- Wardon the lines 1 until they stand at right angles to the sides B, thereby perfecting the corners and also forming the inner portions of the ends of the box when the looking catches C are engaged. The two inner cover flaps E E are turned down on. the lines H H forming a right angle with the sides B B, when the locking catchesE E are engaged. The ends D are turned up on the lines K and brought at right angles to the bottom A, so as to form the outer walls or portions of the box ends. The outer cover flaps F are turned down on the lines L until they rest on the top of the inner cover flaps E when the catches F are engaged.

What 1 claim as my invention is;

A carton made from a single blank of flexible material cut and scored to form the bottom, cover and sides, end flaps on said sides, said flaps being slit in a curved shape, the curve terminating in an enlarged opening, the end flaps forming interlocking end members, inner cover flaps with curved slits for locking the same together, and end flaps on said bottom, said end flaps having curved slits for interlocking the same.
